What is a common sign of lameness in horses that could indicate laminitis?

Heat in the hooves is a common sign of lameness that can indicate laminitis. When a horse is suffering from laminitis, inflammation occurs in the sensitive laminae of the hoof, which is responsible for attaching the hoof wall to the internal structures. This inflammation often leads to increased blood flow to the area, which can manifest as a noticeable heat emanating from the hooves. Owners and caretakers should routinely check a horse's hooves for heat as part of their health assessments, especially if the animal shows signs of discomfort or unusual behavior.

In contrast, while increased energy could be a sign of other issues, it is not typically associated with laminitis. Excessive sweating may result from various conditions or stress factors but is not specific to laminitis. Nasal discharge generally points to respiratory issues, which are unrelated to the hoof and laminitic conditions. Recognizing heat in the hooves can be crucial for early detection and intervention in cases of laminitis, making it an important sign for horse owners and caregivers to understand.
